Functions Of RLDC • Apex Body For Integrated Grid Operation • Responsible for Optimum Scheduling and Dispatch of Electricity • Keep Accounts Of Electricity Transmitted Through Grid • Supervise and Control The Inter – State Transmission System • Ensure Security and Economy In Operation as per the Grid Standards and the Grid Code
Establishment of Modern RLDCsHas Resulted Into: • Considerable Betterment of System Parameters viz., Frequency & Voltage in spite of Minimal Generation Addition • Merit Order Operation, Leading to Overall Economy • State-of-the-art technology in grid operation by introduction of ULD & C Schemes. • Introduction of ABT (Availability Based Tariff), linked to frequency variation • Transparency in grid operation • Quantum leap in intra and Inter Regional Power Exchange and Trading • Infused Grid Discipline
POWERGRID’s Diversification into Telecom • To utilize spare capacity of ULDC schemes and maximize return on its transmission infrastructure, POWERGRID decided to diversify into Telecom • Through an incremental investment • Telecom networks on Transmission Infrastructure • Sturdy & secure • Rodent menace free • Vandalism proof
POWERGRID’s Diversification into Telecom • Only utility in the country providing overhead fibre optic cable for telecom networks • DWDM/SDH equipment deployed • Scalable to Terabit Capacity • Obtained IP-II license in Jan 2001 and ISP Category-A license in May 2003
POWERGRID’s Broadband Network • All India Fibre Optic Network of 20,000 kms, spread over 60 cities including all Metros & major cities • Links under commercial operation • Delhi-Lucknow -Mumbai • Delhi-Ambala-Chandigarh-Shimla-Jallandar-Jammu • Delhi- Jaipur • Ahmedabad-Mumbai-Pune • Mumbai-Hyderabad-Bangalore-Cochin • Within NER • Maintaining availability of 100% on overhead OFC network
POWERGRID’s Broadband Network • Complete network to be in place by 2004 • Chennai June, 2004 • Allahabad, Kanpur, Agra June, 2004 • Kolkatta, NER June, 2004 • Trivandrum Sept, 2004

ULD & C PROJECT: OBJECTIVES • To have • Greater and deeper visibility of the power system under control • Better communication and co-ordination between control centers • Effective management of grid parameters viz. frequency, voltage etc. and better grid security through various SCADA/EMS features resulting in better • Operations scheduling • Operations monitoring and control • Power system analysis • A real time environment for dispatcher training
AVAILABILITY BASED TARIFF CAPACITY CHARGE ENERGY CHARGE ADJUSTMENT FOR DEVIATIONS (U I CHARGE) Where (A) = a function of the Ex-Bus MW availability of Power Plant for the day declared before the day starts x SEB’s % share (B) = MWh for the day as per Ex-Bus drawal schedule for the SEB finalised before the day starts x Energy charge rate (C) = Σ (Actual energy interchange in a 15 minute time block – scheduled energy interchange for the time block) x UI rate for the time block TOTAL PAYMENT FOR THE DAY = (A) + (B) ± (C)
